Researchers from Wuhan University of Technology in China have developed a polymer solar cell with 19.1% efficiency and remarkable stability by blending small-molecule acceptors into polymeric matrices. The incorporation of linearly packed small molecule acceptors disentangled polymeric chains, creating efficient pathways for charge transport and reducing degradation. The resulting devices retained 97% efficiency after 2,000 hours of operation in air, with an extrapolated lifetime exceeding 100,000 hours. This work provides a practical pathway towards commercialization of flexible organic photovoltaics, with various layers including a molybdenum trioxide hole transport layer and a buckminsterfullerene electron transport layer contributing to the cell's success.

Solar, storage to lead record 86 GW of US capacity in 2026
Solar and battery storage are set to account for 79% of 86 GW of new utility-scale capacity planned in the United States in 2026, with analysts projecting one in eight American homes will have solar, many with storage for self-consumption. Distributed small-scale solar generation is increasing, with a focus on integrated energy systems and high battery attachment rates. Renewables and storage are expected to make up 93% of new utility-scale capacity this year, with a significant growth in solar generation. The key focus now is on how quickly the infrastructure can be interconnected to the grid to ensure grid stability and maximize the benefits of these climate solutions.

Bolivia creates net metering scheme for medium-voltage distributed generation
Bolivia's government has approved Supreme Decree 5549, establishing a medium-scale distributed generation category for renewable projects between 1 MW and 6 MW. This decree simplifies procedures for connecting to medium-voltage networks, sets a remuneration scheme for energy injected into the system, and aims to increase the share of renewable energy in the electricity market. It promotes self-consumption, decentralization of generation, and the use of resources such as solar, hydropower, and biomass. Implementation will follow a phased approach, starting with the private sector and later extending to commercial and residential users.

Wind plans for huge South Australia renewables precinct get federal green light
Neoen's Goyder wind and solar project in South Australia has received approval for stages 1 and 2 of the northern section, with plans for 99 turbines and a 600 MW capacity, including a 225 MW/900MWh battery energy storage system. The project aims to achieve over 2.6 GW of wind and solar generation, multiple batteries, and new transmission lines to connect to demand centers, with contracts signed with BHP for wind capacity to power mining operations. The urgent need for climate solutions is emphasized in light of the health and environmental issues related to climate change, including increased heat-related illnesses, the spread of diseases, extreme weather events, and habitat destruction.

Massachusetts’ least-cost 2050 peak power mix is combustion-free: report
A report by Synapse Energy Economics for the Massachusetts Clean Peak Coalition suggests that Massachusetts can fully decarbonize peak generation by 2050 at a lower cost than continuing to run fossil-fuel peaker plants. The report recommends a portfolio of clean peaking resources including demand-side resources, energy storage, and wind generation. Challenges remain in fully decarbonizing the electricity system, particularly with the shift to a winter-peaking system and the current design of ISO New England's capacity market favoring fossil-fuel generators. The coalition is unsure if recent changes to the grid operator's capacity accreditation model will benefit decarbonization efforts in Massachusetts, but a peak generation portfolio combining wind, energy storage, and demand response could serve winter peaks at a lower cost than the current combustion-dominated generation mix. Regulators and policymakers need to focus on energy efficiency, longer-duration energy storage, addressing community concerns around wind siting, and considering climate and public health impacts to build this portfolio cost-effectively and explore alternatives to fossil peakers and combined heat and power plants.

Competition Is Heating Up In The US Energy Storage Space
Form Energy, a startup from Massachusetts, has developed an iron-air battery for long duration energy storage, surpassing Tesla's Megapack 3 in terms of duration. The company secured a 300-megawatt, 100-hour energy storage deal with Xcel Energy and Google, aiming to provide cost-effective, safe, and reliable energy storage solutions for a grid saturated with wind and solar power. Xcel Energy is moving forward with plans to deploy a Form iron-air battery in its energy plan for a new Google data center in Minnesota, pending approval from the Minnesota Public Utilities Commission. The technology involves iron pellets that rust when exposed to air, releasing energy, and can be recharged by applying electricity, with Form Energy receiving funding to establish a factory in West Virginia for mass production of their iron-air batteries.

Google to deploy world’s largest iron-air battery for US data center
Google has partnered with Xcel Energy to implement a 300 MW/30 GWh iron-air battery system in Minnesota, alongside 1.6 GW of new wind and solar energy. Developed by Form Energy, this project aims to offer long-duration energy storage to stabilize intermittent renewables. The iron-air batteries have the capability to store renewables-generated electricity for up to 100 hours, making them a viable alternative to traditional power plants. This initiative is a key component of Google's commitment to decarbonization and meeting the energy needs of the AI era.

How To Use Up Nuclear Waste Generating Electricity
The article discusses a method developed by CERN in the late 1980s/early 1990s to generate electricity using radioactive materials in an Accelerator Driven System (ADS) reactor. This process transmutes radioactive substances into mostly inert waste, reducing the need for long-term storage of nuclear waste. The ADS reactor could potentially use materials like thorium, unenriched uranium, or nuclear waste dissolved in liquid heavy metals to produce electricity for over 500 years. With the development of a particle accelerator by Jefferson Lab, accelerator driven systems may become more feasible, offering a sustainable solution for managing nuclear waste and potentially making conventional nuclear power obsolete.

Con Ed eyes $38B in capital spending through 2030
Consolidated Edison is planning $38B in utility capital investments over five years to support building and transportation electrification, with a focus on solar generation. They are seeing a significant increase in electric vehicle charging and electric heat requests, aiming to invest proactively to meet New York's clean energy goals. To address reliability challenges, Con Ed plans to add 22 new substations by 2034 and grow their investment base by 8.6% annually through 2030. Additionally, they are exploring joint ownership of large-scale renewable generation to advance the state's clean energy standard, with a decision expected by May.
